cdc_ether: add Novatel USB551L device IDs for FLAG_WWAN

2012-05-21T16:40:02+00:00

commit 4e6304b8420aba5311ba21fd68dab2924ae4d91a upstream. Needs to be tagged with FLAG_WWAN, which since it has generic descriptors, won't happen if we don't override the generic driver info.

cdc_ether: Ignore bogus union descriptor for RNDIS devices

2012-05-21T16:40:02+00:00

commit 6eddcb4c82883451aec3be1240f17793370fa62f upstream. Some RNDIS devices include a bogus CDC Union descriptor pointing to non-existing interfaces. The RNDIS code is already prepared to handle devices without a CDC Union descriptor by hardwiring the driver to use interfaces 0 and 1, which is correct for the devices with the bogus descriptor as well. So we can reuse the existing workaround. Cc: Markus Kolb Cc: Iker Salmón San Millán Cc: Jonathan Nieder Cc: Oliver Neukum Cc: 655387@bugs.debian.org Signed-off-by: Bjørn Mork Signed-off-by: David S.

usbnet: fix skb traversing races during unlink(v2)

2012-05-21T16:40:01+00:00

commit 5b6e9bcdeb65634b4ad604eb4536404bbfc62cfa upstream. Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid recursive locking in usbnet_stop()) fixes the recursive locking problem by releasing the skb queue lock before unlink, but may cause skb traversing races: - after URB is unlinked and the queue lock is released, the refered skb and skb->next may be moved to done queue, even be released - in skb_queue_walk_safe, the next skb is still obtained by next pointer of the last skb - so maybe trigger oops or other problems This patch extends the usage of entry->state to describe 'start_unlink' state, so always holding the queue(rx/tx) lock to change the state if the referd skb is in rx or tx queue because we need to know if the refered urb has been started unlinking in unlink_urbs. The other part of this patch is based on Huajun's patch: always traverse from head of the tx/rx queue to get skb which is to be unlinked but not been started unlinking.

asix: Fix tx transfer padding for full-speed USB

2012-05-21T16:39:59+00:00

[ Upstream commit 2a5809499e35b53a6044fd34e72b242688b7a862 ] The asix.c USB Ethernet driver avoids ending a tx transfer with a zero- length packet by appending a four-byte padding to transfers whose length is a multiple of maxpacket. However, the hard-coded 512 byte maxpacket length is valid for high-speed USB only; full-speed USB uses 64 byte packets. Signed-off-by: Ingo van Lil Signed-off-by: David S.

net: usb: smsc75xx: fix mtu

2012-04-27T16:51:20+00:00

[ Upstream commit a99ff7d0123b19ecad3b589480b6542716ab6b52 ] Make smsc75xx recalculate the hard_mtu after adjusting the hard_header_len. Without this, usbnet adjusts the MTU down to 1492 bytes, and the host is unable to receive standard 1500-byte frames from the device. Inspired by same fix on cdc_eem 78fb72f7936c01d5b426c03a691eca082b03f2b9. Tested on ARM/Omap3 with EVB-LAN7500-LC. Signed-off-by: Stephane Fillod Signed-off-by: David S.

USB: Add Motorola Rokr E6 Id to the USBNet driver "zaurus"

commit a2daf263107ba3eb6db33931881731fa51c95045 upstream. Added Vendor/Device Id of Motorola Rokr E6 (22b8:6027) so it can be recognized by the "zaurus" USBNet driver. Applies to Linux 3.2.13 and 2.6.39.4. Signed-off-by: Guan Xin Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

usbnet: don't clear urb->dev in tx_complete

2012-04-02T16:27:17+00:00

commit 5d5440a835710d09f0ef18da5000541ec98b537a upstream. URB unlinking is always racing with its completion and tx_complete may be called before or during running usb_unlink_urb, so tx_complete must not clear urb->dev since it will be used in unlink path, otherwise invalid memory accesses or usb device leak may be caused inside usb_unlink_urb.
